Specification of Letters Patent.

serieu No. 358,197.

in the same plane as Fig. 7 showing the Be it known that I, ALBERT K. COLLINS, sliding bar in released position.

citizen of the United States, residing at Charlotte, N. C., have invented certain new and useful Improvements in Turnstiles, of which the following is a specification.

This -inventionrelates to certain novel and useful improvements in turn stile's.

In carrying out the present invention, it is my purpose to provide a turn stile which may be used in connection with coin controlled apparatus and whereby persons may be permitted to pass through `the turn stile singly in one direction, as coins are deposit-V ed in the coin controlled apparatus, and whereby persons may be permitted to pass through the turn stile in the opposite direction without depositing coins in the coin controlled apparatus, thereby enabling the,

turn stile to be used to control the admission embody comparatively few parts and these so correlated and arranged as to reduce lthe possibility of derangement to a minimum and enable access to be readily had to such parts for the purposes of cleaning and repairing.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claims.

In the accompanying drawings:

'Figure 1 is a view in side elevation of a turn stile constructed in accordance with the present invention.

Fig. 2 is a top plan view of the same, the train controlled apparatus being removed.

Fig. 3 is a horizontal sectional View through the turn stile.

Fig. 4 is a sectional view as taken on lines 4 4 of Fig. 3.

l Y Fig. 5 is a section taken on lines 5 5 of Fig. 8 is a fragmentary horizontal section tened thereto is a colt-lar 3, while encircling the columnv 2 and spaced apart equal distances vertically thereon are annuli 4 provided with radial arms 5. The top annulus 4 lrests upon the collar 3 and passed through the arms 5 are vertical brace rods 6 that act to hold the annuli in proper relative positions upon the column. In the present instance, the arms 5 on each annulus are four in number and are spaced apart equal distances and aline'vertically with the respective arms on the other annuli so that the rods 6 may be passed through corresponding arms to hold the annuli and arms in proper relative positions. Secured to the top annulus 4 and encircling the` column is a ring 7 having the upper edge thereof formed with ratchet teeth 8, while resting upon the ratchet ring 7 and Vsurrounding the column 2'is a ring 9 having the lower edge formed with ratchet teeth 10 adapted to interengage the teeth 8, and the upper edge dicates a substantially U-shaped yoke ar-l ranged across the upper end of the column 2, and the upper extremity of the limbs of the yoke are outturned as at 14 and lie in the recesses 12 respectively and engage the teeth 11 on the upper edge of the ring 9 so as to hold the ring 9 against rotation in one direction and permit rotation thereof in the opposite direction. Formed 'in theupper end ofthe column 2 at diametrically opposite points are recesses 15 arranged in the same plane as the recesses 12 and formed in the side walls of the recesses 15 are alining grooves 16 and secured within the .grooves 16 is a cross bar 17 formed with an elongated slot 18. Disposed below the cross bar 17 and supported upon the bottom walls of the recesses 15 is a slidablebar 19 having ioo Normally, the mitered end 20 of the slid-- able bar 19 is' disposed in thepath of movement of the adjacent lug 22 on the' ring 9, thereby preventing rotation of the ring in one direction, and when the teeth on the lower edge of the'ring 9 are in engagement v with the teeth on the upper edge of the ring 7 the turn stile is held against rotation in one direction. The slidable bar 19 is under the control of suitable coin controlled mechanismand when the proper coin has been deposited in this mechanism and the mechanism operated the pin 21 moves one end of the slidable bar 19 out of the path of movement of the adjacent lug 22 and slides the opposite end of the bar into the path of movement of the lug" 22 opposite. The turn stile may now be rotated andpin the initial movement of the turn stile the lug 22 adj acent to thelast-mentioned end of the bar 19 rides over the mitered end 20 ofy such bar and restores the bar to normal locking position immediately behind the released lug 22 so that after the turn stile has made a quarter of Ya revolution the following lug 22 will engage the locking end of the slidable bar 19 to hold the turn stile against movement until another coin has been deposited.

In this operation of the turn'stile, the two rings 9 and 7 revolve with the turn. stile and the teeth on the upper edge of the ring 9 idle by the outturned ends 14 of the yoke 13. On the other hand, the turn stile may be revolved in the opposite direction at will and in this turning of the stile, the teeth on the upper edge of the ring 7 idlev by the teeth on the lower -edge of the ring 9, while the outturned ends of the yoke 13 hold the ring 9 stationary so as to prevent movement of the ring 9 relatively to the slidable bar 19.

In practice, one side of the turn stile is blind and stationary bars project into the spaces between the arms 5 so as to prevent the passage of persons through the turn stile at this side, while the otherside of the turn stile is designed to control the entrance of personsfto the theater, amusement park or the like, and permit the exit of such persons from the theater or park.

It will be noted that when the slidable bar is once moved out of locking position so as to admit a person to the turn stile, the turn stile will be enabled to make this onequarter of a revolution at any time without necessitating the deposit ofv another coin, even though the turn stile is operated in the opposite direction succeeding the moving of the bar 19 to release position.

While I have herein shown and described one preferred form of my invention by Way umn secured to said base, annular memof illustration, I wish it to be understood that' I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims and without departing from the spirit of the invention. I claim:

1. In a turn-stile, a base, a vertical colbers carrying radially projecting arms rotatably mounted on said column, a ratchet wheel mounted on the uppermost annular member, a ratchet wheel mounted on said column and -superimposed on said firstnamed ratchet wheel, and means coperating with said ratchet wheels to lock the annular members against rotation. f
